Would GTG with towel pull ups be to much for grip work? Or should you train the grip just like anything else. I am looking to improve my grip for BJJ. I have a 90# throwing dummy and a judo gi. What if just grabbed him up by the gi and hauled him around for a while? I am waiting for the snow to leave here in MN and for the ground to not be so soggy and it is Farmers walk and pulling a sled with a 2" rope.

I have an old Gi that is in the garage and I do lapel P/U's. I think the towel might be thicker then the lapel and would be a different kind of adaptation. I also do static holds with it where I will hang from the Gi for time or get at the top of a P/U and do an entire body crunch and hold that for time like I was doing a choke. I think that length of time you can apply a solid grip is more valuable than maximal strength when grabbing. Since everything is so dynamic in BJJ and you are always moving I want to be able to grab a collar and use that to control my opponent no matter how he moves. Does that make sense?

I could not imagine doing GTG with it though as my hands hurt pretty much all the time from training. I haven't decided if I am getting old or what. Heck maybe I need to do GTG. I definitely will be doing a ton of Gi P/U's in front of this next tournament.

I'm a rockclimber, where grip is also an important tool. A lot of people use hangboards and work either pullups or static hangs with their hands in all sorts of positions. It's easy to injure yourself on these, however.
